Title: Preference-aware Integration of Temporal Data
A complete description of an entity is rarely contained in a single data source, but rather, it is often distributed across different datasources. Applications based on personal electronic health records,sentiment analysis, and financial records all illustrate that significant value can be derived from an integrated, consistent, and queryable profile of entities from different sources. Even more so, such integrated profiles are considerably enhanced if temporal information from different sources is carefully accounted for. In this talk, we describe a preference-aware union operator that is capable of consistently integrating data that may contain multiple dimensions of time and upholds important algebraic identities, which makes it particularly suitable for data integration: PRAWN produces the same integrated outcome, modulo representation of time, regardless of the order in which data sources are integrated.
